Question

我正在尝试运行Shiny的示例代码，app.R。如果我点击＆＃34;运行App＆＃34;，我有以下错误：

Error in normalizePath(path.expand(path), winslash, mustWork) : 
  path[1]="XXXXXXX": Access is denied

根据我的搜索，它是一个RStudio问题，但我的其他工作正常。

这是R代码：

require(shiny)
require(shinythemes)
require(DT)
require(DBI)
source("Shiny/global.R")


server <- function(input, output, session) {


  # Expression that generates a histogram. The expression is
  # wrapped in a call to renderPlot to indicate that:
  #
  #  1) It is "reactive" and therefore should re-execute automatically
  #     when inputs change
  #  2) Its output type is a plot

  output$distPlot <- renderPlot({
    x    <- faithful[, 2]  # Old Faithful Geyser data
    bins <- seq(min(x), max(x), length.out = input$bins + 1)

    # draw the histogram with the specified number of bins
    hist(x, breaks = bins, col = 'darkgray', border = 'white')
  })
}

#==== UI  ====

ui <- shinyUI(
  fluidPage(

    # Application title
    titlePanel("Hello Shiny!"),

    # Sidebar with a slider input for the number of bins
    sidebarLayout(
      sidebarPanel(
        sliderInput("bins",
                    "Number of bins:",
                    min = 1,
                    max = 50,
                    value = 30)
      ),

      # Show a plot of the generated distribution
      mainPanel(
        plotOutput("distPlot")
      )
    )
  )

)

shinyApp(ui = ui, server = server, onStart = "global.R")

我没有真正更改示例代码，sessioninfo（）看起来像这样：

locale:
[1] LC_COLLATE=German_Switzerland.1252  LC_CTYPE=German_Switzerland.1252    LC_MONETARY=German_Switzerland.1252
[4] LC_NUMERIC=C                        LC_TIME=German_Switzerland.1252

有没有办法解决这个问题？

normalizePath出错（path.expand（path），winslash，mustWork）
